Non-Contact Voltage Sensing - Amprobe AM-520 Mode D'emploi

Non-Contact Voltage Sensing

1. To avoid personal injury or damage to the Meter, do not test on un-
insulated high voltage wires.
2. Buzzer will sound and screen will display "OL" when sensing AC voltage
between 90V and 600V
3. Do not test on hazardous live wires higher than AC 750V
4. Before and after hazardous voltage measurements, test the Meter by
approaching to a known source such as a line AC voltage or outlet to
determine proper operation. See below figure.
Buzzer will sound when the detected voltage is ≥90V, and the buzzer will be
on.The distances between the wire and the meter should be ≤8mm.

At NCV mode, LCD will display OL. No test lead connection are required for
NCV measurement.
